(Normal blood sugar at bedtime, low blood sugar overnight, high blood sugar in the morning)
Make sure to have a snack before bedtime
Rebound hyperglycemia due to a drop in glucose levels overnight because of evening insulin administration.
As a result – glucagon is released by the pancreas, the liver releases glucose, thus, causing hyperglycemia in the
morning.
Treat by decreasing the evening insulin dose and/or provide the patient with a bedtime snack of complex carbs. Calm
pt = complex

Always count the rate first, and then the rhythm
Count QRS complexes in a 6 second strip and multiply by 10 to get the HR
HR <60 = Sinus Bradycardia
HR 60-100 = Normal Sinus Rhythm
>100 = Sinus Tachycardia
PR interval = 0.12-0.20 (Atrial depolarization)
QRS interval = 0.08-0.12 (Ventricular depolarization)
T wave = Ventricular repolarization
18. Know Furosemide (Look in Davis drug guide, know what is in RED)
